I have a 15 gallon CH air compressor. it will build up pressure fine but will not kick back on when the pressure drops from use. it kicks off at 125psi like it should but when it kicks off it also trips the safty switch. I got to looking and found that the "motor reset switch" gets triped every time. does anyone know what is wrong with it. once I push the button back in the motor starts. it does this every time.
